Conflict with Sponge

[HienVienGaming -VietNam]

The problem was make on Sky Factory 4 modpack.

Small code:

com.bloodnbonesgaming.triumph.events.CoreEventHandler.isChildOrSelfVisible(CoreEventHandler.java:414)
com.bloodnbonesgaming.triumph.events.CoreEventHandler.onAdvancementVisibilityCheck(CoreEventHandler.java:214)

When I try to use Triumph + Together Forever in SpongeForge server, when i try to craft item that trigger the advancement, Triumph + ToFe will lookup for the <null> player which make Sponge can’t understand what was the mod doing.

Log is get upload, take a look on it.
